Answer: no
Explanation: a compound is two DIFFERENT chemically bonded. thus two green spheres would represent a molecule
The enthalpy of reaction for the given above and any other given can be calculated through the equation,
Hrxn = H(product) - H(reactants)
From reliable sources, the values of H of the substances.
H(NO) = 90.25 kJ/mol
H(O2) = 0 kJ/mol
H(NO2) = 33.18 kJ/mol
Substituting the known values,
Hrxn = (2)(33.18 kJ/mol) - (2)(90.25 kJ/mol)
Simplifying,
Hrxn = -114.14 kJ
<em>ANSWER: -114.14 kJ</em>
When the salt gets added to the coke it changes the balance of the its chemistry and forces the release of carbon dioxide bubbles.
the answer is true the first one
